Use of Far-Field Diverting Compositions For Hydraulic Fracturing Treatments

ABSTRACT

The present disclosure provides hydraulic fracturing treatment fluid compositions and systems, and methods of hydraulic fracturing hydrocarbon-bearing formations and/or increasing fracture complexity of a fracture network within a subterranean formation.

FIELD

The present disclosure is directed, in part, to far-field diverting compositions and systems and methods of their use in hydraulic fracturing hydrocarbon-bearing formations and/or increasing fracture complexity of a fracture network within a subterranean formation.

BACKGROUND

Subterranean wells (e.g., hydrocarbon producing wells, gas producing wells, oil producing wells, and the like) are often stimulated by hydraulic fracturing treatments. In traditional hydraulic fracturing treatments, a treatment fluid, which may also function simultaneously or subsequently as a carrier fluid, is pumped into a portion of a subterranean formation (which may also be referred to herein as a “formation”) at a rate and pressure sufficient to break down the formation and create one or more fractures therein. Typically, particulate solids, such as graded sand, are suspended in a portion of the treatment fluid and then deposited into the fractures. The particulate solids, known as “proppant particulates” (which may also be referred to herein as “proppants” or “propping particulates”) prevent the fractures from fully closing once the hydraulic pressure is removed. By keeping the fractures from fully closing, the proppant particulates aid in forming conductive paths through which fluids produced from the formation flow, referred to as a “proppant pack.”

Fracture complexity may be enhanced by stimulation (e.g., fracturing) operations to create new or enhance (e.g., elongate or widen) existing fractures. In such cases, the newly formed fractures may remain open without the assistance of proppants or micro-proppant particulates due to shear offset of the formation forming the fractures, or may have included therein proppant particulates, depending on the size of the fracture, to assist in keeping them open after hydraulic pressure is removed. The inclusion of proppant particulates in the fractures, new or natural, may increase the conductivity of a low permeability formation.

In some cases, subterranean treatment operations (e.g., stimulation, proppant placement, and the like), may be supplemented with enhanced hydrocarbon recovery techniques. Such enhanced oil recovery techniques may operate to enhance the conductivity of fractures. One such technique is acidizing, which involves injecting an acid (e.g., hydrochloric acid) into a subterranean formation to etch channels or create microfractures in the face of the formation and/or within an existing macrofracture or microfracture, thereby enhancing the conductivity of the formation. The acid may create a branched, dendritic-like network of channels through which produced fluids may flow. Another such technique is far-field diversion, which involves injecting a degradable and/or dissolvable diverting material (e.g., aliphatic polyesters, phthalic anhydride, and benzoic acid) into a subterranean formation to bridge off and prevent additional fluid flow into higher permeability zones, allowing other well treatment fluids to be injected into other areas of lesser conductivity, and ultimately enhancing the conductivity of the formation. These diverting materials, however, are often expensive and, therefore, are employed at low concentrations. In addition, diverting agents often burden conductivity in productive zones once the face of such zones have been plugged or blocked with a diverter.

In some embodiments, any of the far-field diverting compositions can be introduced into the formation through the hydrojetting tool and out the hydrojetting nozzle at a rate and pressure sufficient to create or enhance the diversion of fluids in the formation.

In various embodiments, systems configured for delivering any of the far-field diverting compositions described herein to a formation are described. In various embodiments, the systems can comprise a pump fluidly coupled to a tubular member, the tubular member containing any of the far-field diverting compositions described herein.

The pump may be a high pressure pump in some embodiments. As used herein, the term “high pressure pump” will refer to a pump that is capable of delivering a fluid downhole at a pressure of about 1000 psi or greater. A high pressure pump may be used when it is desired to introduce any of the far-field diverting compositions to a subterranean formation at or above a fracture gradient of the subterranean formation, but it may also be used in cases where fracturing is not desired. In some embodiments, the high pressure pump may be capable of fluidly conveying particulate matter, such as any of the far-field diverting compositions described herein, into the formation. Suitable high pressure pumps include, but are not limited to, floating piston pumps and positive displacement pumps.

In other embodiments, the pump may be a low pressure pump. As used herein, the term “low pressure pump” will refer to a pump that operates at a pressure of about 1000 psi or less. In some embodiments, a low pressure pump may be fluidly coupled to a high pressure pump that is fluidly coupled to the tubular member. That is, in such embodiments, the low pressure pump may be configured to convey any of the far-field diverting compositions to the high pressure pump. In such embodiments, the low pressure pump may “step up” the pressure of any of the far-field diverting compositions before reaching the high pressure pump.

In some embodiments, the systems described herein can further comprise a mixing tank that is upstream of the pump and in which the far-field diverting composition is formulated. In various embodiments, the pump (e.g., a low pressure pump, a high pressure pump, or a combination thereof) may convey the far-field diverting composition from the mixing tank or other source of the far-field diverting composition to the tubular member. In other embodiments, however, the far-field diverting composition may be formulated offsite and transported to a worksite, in which case the far-field diverting composition may be introduced to the tubular member via the pump directly from its shipping container (e.g., a truck, a railcar, a barge, or the like) or from a transport pipeline. In either case, the far-field diverting composition may be drawn into the pump, elevated to an appropriate pressure, and then introduced into the tubular member for delivery to the formation.

It is also to be recognized that the disclosed far-field diverting compositions may also directly or indirectly affect the various downhole equipment and tools that may come into contact with the far-field diverting compositions during operation. Such equipment and tools include, but are not limited to, wellbore casing, wellbore liner, completion string, insert strings, drill string, coiled tubing, slickline, wireline, drill pipe, drill collars, mud motors, downhole motors and/or pumps, surface-mounted motors and/or pumps, centralizers, turbolizers, scratchers, floats (e.g., shoes, collars, valves, etc.), logging tools and related telemetry equipment, actuators (e.g., electromechanical devices, hydromechanical devices, etc.), sliding sleeves, production sleeves, plugs, screens, filters, flow control devices (e.g., inflow control devices, autonomous inflow control devices, outflow control devices, etc.), couplings (e.g., electro-hydraulic wet connect, dry connect, inductive coupler, etc.), control lines (e.g., electrical, fiber optic, hydraulic, etc.), surveillance lines, drill bits and reamers, sensors or distributed sensors, downhole heat exchangers, valves and corresponding actuation devices, tool seals, packers, cement plugs, bridge plugs, and other wellbore isolation devices, or components, and the like.
